Class SignedJwtAssertionCredentials

Credentials object used for OAuth 2.0 Signed JWT assertion grants.
This credential does not require a flow to instantiate because it represents
a two legged flow, and therefore has all of the required information to
generate and refresh its own access tokens.
SignedJwtAssertionCredentials requires either PyOpenSSL, or PyCrypto 2.6 or
later. For App Engine you may also consider using AppAssertionCredentials.
